So the poor hath hope - From the interposition of God. They are not left in a sad and comfortless condition. They are permitted to regard God as their protector and friend, and to look forward to another and a better world. This sentiment accords with all that is elsewhere said in the Scriptures, that the offers of mercy are specially made to the poor, and that they are especially the objects of the divine compassion.
And iniquity stoppeth her mouth - That is, the wicked are confounded when they see all their plans foiled, and find themselves entangled in the snares which they have laid for others. A similar sentiment occurs in Psalms 107:41-42 :
Yet setteth he the poor on high from affliction,
And maketh him families like a flock.
The righteous shall see it and rejoice,
And all iniquity shall stop her mouth.”
It is to be remembered that Eliphaz states this as the result of his own observation, and as clearly demonstrating in his view that there is a superintending and overruling Providence. A careful observation of the course of events would lead undoubtedly to the same conclusion, and this has been embodied in almost every language by some proverbial sentiment. We express it by saying that “honesty is the best policy;” a proverb that is undoubtcdly founded in wisdom. The sentiment is, that if a man wishes long to prosper, he should pursue a straight-forward and an honest course; that cunning, intrigue, underhanded dealing, and mere management, will sooner or later defeat itself, and recoil on the head of him who uses it; and that, therefore, if there were no higher motive than self-interest, a man should be honest, frank, and open. See this argument stated at greater length, and with great beauty, in Psalms 37.
